I agree with most of what you are saying here. Let me tell you that most of the examples of what you see as "puppy" would be IMO (or my zoo) monkey behavior. The monkey isn't vulnerable. The monkey is young, fun, naughty,horny in need of discipline etc. I would call what you describe as "lion with thorn in paw" as a man protecting his puppy with his wolf. The examples you gave of true vulnerability are what I would call puppy behavior. Obviously, real life puppies behave in ways that are both monkey and vulnerable so it's just a matter of perspective. I would also say that the way you are viewing the men's profiles on Match is a matter of perspective. First off, I would point out that you are taking it upon yourself to look at their profiles rather than putting your own profile out there for them to look at. Therefore, you are viewing them as monkeys signaling availability rather than men responding to your signal of availability. By keeping yourself in a position of control rather than vulnerability you are making the same mistake as you made in your marriage, you are causing the men to vibe monkey because you are vibing lioness and thereby making them unattractive. More than half of the population of single people in America participate in online dating so it isn't the case that the sites are just loaded with losers. If what you want is a lion to mate with your lioness, then what you need to do is put out a strong profile that vibes that way and wait for a lion to respond appropriately.
